TOGGLE-IBOLT.

Application filed November 30, 1910.

Specification of Letters Patent.

Patented Jan. 13,1914.

Serial No. 594,906.

To all whom it may concern:

Be it known that I, HENRY B. NEWHALL, a citizen of the United States, and a resident of Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Toggle- Bolts, (Case A,) of which the following is a specification, taken in connection with the accompanying drawing, which forms a part of the same.

This invention relates to toggle bolts and more particularly to the head of a toggle bolt which will permit it to directly co'operate either with the head of an ordinary bolt or with the nut of such a bolt. Usually, though not necessarily, this bolt is an ordinary stove bolt of commerce which may be sold in combination with the head of the toggle bolt, or the head may be sold separately, to be later combined with the bolt by the purchaser. Therefore my toggle bolt comprises the combination of the head and the bolt as well as the head which can be sold as a separate article of manufacture.

In the accompanying drawing I have shown illustrative embodiments of my invention in which the same reference numerals refer to similar parts in the several figures.

Figure 1 is a vertical section through the head of the toggle bolt, the support and the article supported, the stem or bolt and nut being shown in side elevation; Fig. 2 is a side elevation of the toggle bolt, the head of the stem or bolt being shown directly cooperating with the toggle head; Fig. 8 is a detail perspective view of one form of the head of my toggle bolt; Fig. 1 is a plan view of the blank from which one form of head is made; Fig. 5 is a side elevation of the toggle bolt, the nut of thestem or bolt being shown directly cooperating with the head, which in this form is provided with three staggered assembling slots; Fig. 6 is a detail perspective view of a modification of the head, showing the blank bent around to form substantially a cylinder; and Fig. 7 is a side elevation of a modification.

In the illustrative embodiments of this invention shown in the drawing, 1 is a toggle bolt including a head 2 and a stem or bolt 3; the head engaging means 4 and 5 are ordinarily the head and nut, respectively, of an ordinary bolt. The head 2 is preferably formed from a blank 6 of stamped sheet metal within which I form preferably a substantially center aperture 7 and angular apertures 8, 8. I connect one of the apertures 8 with another aperture or slot 9 extending toward the end 10 of the blank. From this end 10 extending inward and staggered with relation to the slot 9, I form another slot 11. When this blank 6 is bent into the shape required to form the head 2, the center of the blank forms a body member 12 and the side members 18 and 14 are either bent down substantially at right angles to the body member 12 or they may be, as in Fig. 6, curved so as to form with the body member 12 a substantially closed, cylindrical head 15, Fig. 6.

In assembling my toggle bolt the nut 5 may be mounted within the head 2 and allowed to rest upon the pivoting shoulders 16, 16, Fig. 5, when the stem 3 can be screwed into the nut 5. After the head has been inserted through the aperture 17 of the support 18, it will drop down into substantially right angles to the stem 8, Fig. 1, which will cause the nut 5 to move from the pivoting shoulders 16, 16 to the locking shoulders 19,

19. Upon rotating the stem 3, the supported article 20 will be firmly clamped and held to the support 18 which may be terra cotta, brick, metal work, cornice work, wire lathe, masonry, or other suitable support.

In practice I have found that by providing the head 2 with staggered assembling slots 9 and 11, it will co6perate directly with either the head 4 of the stem or the nut 5 and further, that thisis a very economical way in which to manufacture the head. The pivoting and locking shoulders 16 and 19 of the head have to be located a certain distance from each other which must be substantially the diameter of the head 4 of the stem 3, if the head is to be used interchangeably with the nut 5, for otherwise the head of the stem would simply drop between the side members 18 and 14 without engaging on the pivoting and locking shoulders 16 and 19. If

the space 21 between the side members 13 and 14 is properly adjusted so as to permit the head 4 to rest upon these pivoting and locking shoulders it would be impossible to assemble the head 4 within the toggle head 2 without springing the side members 18 and 14 away from each other; but as they are often of considerable thickness and strength it would be practically impossible to do this without proper tools, which would make the operation so slow and costly that it would be practically prohibitive. By my invention, however, I can assemble the head 4 of the stem and mount it on the pivoting and locking shoulders 16 and 19 by simply inserting the head 4 through the end 10 of the head '2, a portion of the head 4 passing down the slot 11 until it reaches substantially the end 22 of that slot, when by simply pressing the stem 3 in the opposite direction, toward the staggered slot 9, the head 4 is caused to move slightly in that direction and a portion of it passes down the slot 9 until the head reaches the pivoting and locking slots 16 and 19 where it will be securely held until it is desired to disassemble the stem from the toggle head 2 when the operation of assembling is reversed by pressing the head 4 from the slot 9 to the slot- 11 and then out partly through that slot.

It, of course, is understood that in using the nut to directly engage with the pivoting and locking shoulders it can be mounted on them and then the stem 3 can be screwed within the nut as shown for example in Fig. 5. In this manner either the nut or head 4 can be left on the exterior of the supported article 20 as the exigencies of the case may demand.

In those cases where it is necessary or desirable tor the appearance of the work, or the cost of drilling the aperture 1?, to make the head of the toggle bolt of as small a diameter as possible commensurate with the load it is to support, 1 form it into substantially a cylinder by bending down and curving the side members 13 and 14 as well as curving the body member 12, thereby forming a shield 15, Fig. 6, within which the same staggered slots 9 and 11 are formed.

In some cases I may add to the number of the assembling slots as in Fig. 5 where in addition to the slot 9 1 form two other assembling slots 23 and 24, it, of course, being understood that the number may be multiplied as may be round desirable. In other cases I may use merely one assembling slot 25, Fig. 7, which extends from the end 10 of the head 2 to one of the pivoting shoulders.

Having thus described this invention in connection with several illustrative embodiments thereof to the details of which I do not desire to be limited, what is claimed as new and what it is desired to secure by Letters Patent is set forth in the appended claims:

1. In a toggle bolt, the combination of a bolt provided with a head adapted to be positively and detachably held to the toggle head, a toggle head having longitudinally extending spaced side members, the space between the side members being less than the width of the bolt head, a nut, and means to permit either the bolt head or nut of the bolt to interchangeably and directly cooperate with the toggle head and be secured thereto against accidental disengagement.

2. A head for a toggle bolt provided with side spaced members extending longitudinally of the main portion of the head, the space between the side members being less than the width of the head of the bolt with which it is to be used, said side member or members being provided with means to receive the head of a bolt of greater width than the space between the side members, and other and additional locking means on the toggle head to cooperate with either the head of the bolt or its nut to secure the bolt and toggle head together and against acciddental disengagement.
